COMBINED STEAM'AND HOT-WATER HEATER.

SPECIFICATION forming part of Letters Patent 1\T o. 681,226, datedAugust 27, 1901. `f i i Application filed April 20, 1901. `Seriallll'o.56,726. (No model.)

T @ZZ whom t may concern.:

Connecticut, have invented certain new and useful Improvements inaCombined Steam e 1 l andHot-Water Heater, of which the following is aspecification.

My invention relates to a combined hotwater and steam heater; and it hasfor its object the provision of means whereby the ordinary boiler now inuse for steam-heating pure l poses only may be so divided that it may beutilized both as a steam-heater and a hot-water heater.

In the sectional steam-boiler now employed ,a the` sections or manifoldsthereof are connected in assembling the boiler by through-r bolts, andin the steam-dome of the boiler and at its lower part these manifoldsare y made to communicate with each other by what are known in the tradeas push-nipa ples, which are castings or fixtures connecty ing onemanifold with another manifold in order to afford free steam and waterconnec-` tion between all of the sections of which the 1"* 1 boiler iscomposed.

to employ steam for heating one part of a` t building and hot water forheating another i It frequently happens that it is desirable part ofsaid building; and myinvention is designed particularly forenabling'both the a x steam and hot-water systems to beutilized, asdesiredin;the same building and with but the use of a single boiler.'

My inventionmay be carried into effect in many ways, and the main objectthereof is to so divide steam-boilersof `various kinds now e in use thatone part of the boiler maybe utilized as a steam-heater 'and the otherpart thereof as a hot-water heater.

Incarrying out the invention I may employ aset of push nipples, havingdial phragms or partitionsfor dividing the boiler into sections, or whatare known as blind sections or manifolds may be employed, or a manifolddividing the boiler into the desired sections, said manifold having alongitudinal a, partition for accomplishing the same purpose,

maybe employed, the invention not being t limited to any specific devicefor carrying it i y into edect.

is a View similar to Fig. 5, representing another modiication in whichone of the sections or manifolds is provided with a longitudinaldiaphragm or partition.

Like characters designate similar parts throughout the several views.

Referring to the drawings, the numeral `designates a common form ofsectional steamboiler to which my invention is shown applied, and thenumerals 12 the manifolds or sections which are united by longitudinalrods or bolts 13 in assembling the boiler. These manifolds are hollow toafford a circulation of the water employed for generating steam, and theapparatus is provided with a steam-dome 14 with lateral pipes 15 andwith a vertical pipe 16 for containing water. A water-supply pipe 17,containing a valve 17', by which the entrance of water is regulated, andthe usual return-pipe 1S will also be found illustrated in Figs. 1 and2.

l Designated by the numeral 19 is .an im-` proved form of push-nipple,which serves `to divide the heating apparatus illustrated into sectionsA and B, respectively, the section A serving as a steam-heater and thesection B as ahot water heater. 4 lnipples are each provided with adiaphragm These push- 19', and when placed in the openings provided fortheir. reception in the sections or manifolds 12,'as illustrated inFigs. 1 and 2, serve to divide the apparatus into the two compartt mentsA and B, respectively, above speciiied,

`in the former of which steam is generated for the purpose of heating bythat agent and in the latter of whichjhot water is relied `upon as theheating agent. N

Connected'to the hot-,water section B of the apparatus are the usualsupply andreturn pipes 22 and` 23, respectively, and leading from bothsections of said apparatus are pipes Irs 24 and 25, respectively, forsupplying steam and hot water to the parts of the building desired. Y

While nipples of a particular kind are illustrated, it is distinctly tobe understood that the invention is not limited to the form of nippleshown, for other forms containing a diaphragm or partition may beemployed as substitutes without departure from the scope thereof.

The usual grate 26 for receiving fuel is illustrated inFig. ,2, and theproducts of combustion emerge from the apparatus through the iiue 27 andpipe 28, leading to the chimney.

In Fig. I have illustrated a modification in which the push-nipples,with diaphragms, are dispensed with, and what is termed a "blind sectionor manifold 29 is inserted between two of the manifolds 12 for thepurpose of dividing olf or separating one of the sections of theapparatus from the other.

In the modication illustrated by Fig. 6 a section or manifold 30, havinga longitudinal partition 31, is employed for eecting the same purpose.

Push-nipples 32 of ordinary form are illustrated in the several viewsfor connecting the steam-dome of one section of the apparatus with thevarious manifolds in the section A, and similar push-nipples are alsoemployed for permitting a circulation of the hot Water in the section B,as illustrated in Fig. 1.

It frequently happens that it is deemed necessary or desirable toutilize one section of the apparatus for steam heating purposes and theother section for hot-water heating, as above stated, and by dividingthe boiler in the manner set forth I am enabled to accomplish theseresults with ease and facility.

While the invention is shown on atype of apparatus in which the sectionsor manifolds are arranged vertically, it is distinctly to be understoodthat it is not limited thereto, for it may be employed with variousforms of boilers now on the market, whether of the vertical, horizontal,or other types, or with sections cast solid.

The blind nipples 19 containing the diaphragms or partitions 19 may beapplied to any section of the boiler required without departure from theinvention, and either the rear or front section of said boiler may beutilized as the hot-water section or the steamsection, if desired.

Having thus described my invention, what I claim isl. Inaheatingapparatus,the combination, with a boiler, of closed nipplesfordividing said boiler into sections, one of said sections to beutilized for generating steam fora steamheating system, and the other ofsaid sections as a means for supplying hot water to a hotwater heatingsystem.

2. The combination, with a boiler composed of separate sections, ofclosed nipples for dividing said sections so that one part of the boilermay be utilized as a steam-heater andthe other part of said boiler as ahotwater heater.

3. In an apparatus of the class specified, the combination, with aboiler composed of sections or manifolds, of means for uniting saidmanifolds; and closed push-nipples for separating a part of saidVmanifolds fron another part thereof. v

4. The combination, with a boiler composed of tubular sections ormanifolds, each of said manifolds having a series of openings, of meansfor connecting one manifold with another manifold, to permit acirculation of the heating agent; and closed push-nipples for dividingoff one set of manifolds from another set, whereby the boiler isseparated into sections, one of which may be employed as a steam-heaterand the other as a hot-water heater.

5. The combination, with a boiler composed of manifolds perforated atdierent points to permit a circulation of the heating agent, of opennipples inserted in said perforation; and means located between twoopposing open nipples for dividing said boiler into sections, wherebyone part of the boiler may be utilized as a steam-heater Vand the otherpart thereof as a hot-water heater.

6. The combination, with a boiler composed of sets of manifolds, ofmeans for uniting said manifolds; means for connecting the manifolds toafford a circulation of the heating agent and closed nipples fordividing one set of manifolds from another set, so that the sections ofthe boiler may be utilized for different purposes.`

7. The combination, with a boiler composed of sections, of closednipples for uniting said sections; means for separating one section fromanother section, and supply and return pipes connected with eachsection.

8. The combination, with a boiler composed of tubular manifolds, of aset of nipples for connecting these manifolds at dierent points; and aset of blind nipples for dividing the boiler into sections, one sectionto be employed as a hot-Water heater and the other section as asteam-heater; and supply and return pipes for both sections.

9. The combination, with a boiler composed of manifolds, of open nipplesuniting certain of said manifolds at different points;- and closed orblind nipples dividing one set of manifolds from another set 0fmanifolds.

10. In a combined steam and hot-water boiler the combination, withmanifolds having openings at their upper ends and other openings intheir lower ends; of push-nipples connecting one manifold with another,and located in said openings; and push-nipples having diaphragms locatedin the openings of two adjacent manifolds, and serving to separate oneset of manifolds from another set, thereby to divide the boiler intosections for utilization as steam and hot-water heaters.-

11. The combination, with a series of ver- IIO IZO

tubular sections, each section having an opening for the passage ofWater, of a parti- 1o tion adapted to be located between the op posingopenings, substantially as specified.
